As an Apostolosian, they are gilled and have blue-green, slightly iridescent scales on their neck and face.

Massalia d'Argent[note 1] resembles Fan Bingbing in a men's suit, with a high forehead, straight eyebrows, and small, focused facial features. Their hair is high on top and slicked backwards, and shorter on the sides. They're wearing dress pants with really thick suspenders and a lacy blouse with wide cuffs that open up. Over that they wear a black cape with a silver lining, tied by a ribbon tie in a bow (with the long ends hanging unevenly).[1]
